joglomedia edited a comment on issue #1664: ngx_pagespeed breaks png image on Chrome, no issue with other browsers URL: https://github.com/apache/incubator-pagespeed-ngx/issues/1664#issuecomment-533965690 i see that your logo file is in webp https://babynews.de/wp-content/uploads/2019/02/xBabynews-Logo-Turquoise-V2.png.pagespeed.ic.NNX9kzHryG.webp did you enable pagespeed image compression? I think, not all browser already support webp i suggest you to disable webp conversion on pagespeed conf, try this pagespeed DisableFilters convert_jpeg_to_webp,convert_to_webp_lossless,convert_to_webp_animated,recompress_webp; also, when I visiting your logo file it is 404 not found https://babynews.de/wp-content/uploads/2019/02/xBabynews-Logo-Turquoise-V2.png may be typo? just guessing, your correct logo url is here (without x) https://babynews.de/wp-content/uploads/2019/02/Babynews-Logo-Turquoise-V2.png
